Kinematical correlations via -Poincaré coproducts
Mohammad Ali Gorji, Babak Vakili
We study a kinematical consequence of the Hopf-algebraic momentum composition law in -Minkowski spacetime. The same curved momentum space can be described in different coordina…
Covariant scalar-tensor theories beyond second derivatives
Mohammad Ali Gorji, Pavel Petrov, Karim Noui
We propose a covariant, gauge-independent construction of foliation-based scalar-tensor theories, yielding diffeomorphism-invariant operators involving only gradients on the hypers…
A no-go theorem in bumblebee vector-tensor cosmology
Carsten van de Bruck, Mohammad Ali Gorji, Nils A. Nilsson +2
Bumblebee models, a class of vector-tensor theories in which a vector field acquires a nonzero vacuum expectation value that spontaneously breaks spacetime symmetries, are ubiquito…
Linear Higher-Order Maxwell-Einstein-Scalar Theories
Mohammad Ali Gorji, Shinji Mukohyama, Pavel Petrov +1
In the context of the Higher-Order Maxwell-Einstein-Scalar (HOMES) theories, which are invariant under spacetime diffeomorphisms and gauge symmetry, we study two broad subcl…
